XmlPrime 1.2

XmlPrime is an XML Processor for the Microsoft .NET platform versions 2.0 or later. It builds upon the classes in the System.Xml System.Xml System.Xml namespace and provides up-to-date standards compliant implementations of XQuery 1.0 and XPath 2.0.

Implemented standards

XmlPrime implements the following W3C standards.

Change log

Version 1.2.0

Queries can now be evaluated directly to a serializer, avoiding building an intermediate representation.
Push-based evaluation has been implemented for all expressions, and is used for all expressions that are determined to be strict.
Added the (# xp:eager #) pragma to force eager evaluation.
import schema now ignores location hints if the namespace is already statically available.
Imported schemas that fail to compile are no longer added to the available schema set.
Fixed an exception when evaluating treat as empty-sequence() in some circumstances, and improved optimization of type constraints.
Corrected behaviour of MoveToId MoveToId MoveToId for constructed nodes.
Updated liveness analysis to fix problems when using partially evaluated lazy variables in join operations.
Avoided distinct-doc-order for unions such as (@*|node()).
Minor improvements to error messages.
Many small performance improvements.

Version 1.1.0

Completely new serialization implementation.
- Serialization interface now much closer to XmlWriter XmlWriter XmlWriter. There are some breaking API changes in the XmlPrime.Serialization XmlPrime.Serialization XmlPrime.Serialization namespace.
- A new serialization method has been added which allows for serialization of Canonical XML 1.0.
- XmlWriter XmlWriter XmlWriter instances can be created with the full set of serialization settings.
- Some new serialization parameters have been added.
XmlPrime now only requires .NET Framework 2.0, rather than 3.5.
Added XmlPrime extension methods for .NET Framework 3.5 to give a simple way of executing XPath 2.0 expressions.
Added some more constructors to XdmDocument XdmDocument XdmDocument, to match XPathDocument XPathDocument XPathDocument.
Removed IXPathNavigable IXPathNavigable IXPathNavigable overloads for methods taking XPathItem XPathItem XPathItem, as this was causing calls with XPathNavigator XPathNavigator XPathNavigator to be ambiguous.
Reverse axes were previously being cached and reversed. This is now skipped if the results are not needed in document order - eg. for /ancestor::*[1]
Improved optimization of fn:data applied to constructed nodes.
Conformance to latest errata regarding in-scope schema types from modules.
Bug fixes:
- XQuery parsing changed to reflect erratum regarding the leading-lone-slash constraint.
- The order comparison of navigators over XdmDocument XdmDocument XdmDocument instances was incorrect for namespace nodes.
- The fn:base-uri, fn:data and fn:node-name functions behaved incorrectly for namespace node arguments.
- The parsing of URI ports was incorrect in AnyUri AnyUri AnyUri.
- The UserInfo UserInfo UserInfo property was truncating the first character
- Empty document nodes were incorrectly causing spaces to be inserted between sequences of atomic values when constructing an element's content
- XPathNavigator XPathNavigator XPathNavigator instances were sometimes not being cloned when evaluating a query to a single node, leading to the returned navigator pointing to the wrong node.
- Fixed some places where the static types of expressions were not being correctly updated during optimization, causing a NotSupportedException NotSupportedException NotSupportedException or ArgumentNullException ArgumentNullException ArgumentNullException at runtime.
- In some cases function specialization was causing fn:subsequence to throw a NotSupportedException NotSupportedException NotSupportedException at runtime.
- The optimized form of fn:sum($x to $y) was producing xs:decimal values instead of xs:integer values.
- fn:distinct-values was missing an evaluator to produce XPathItem XPathItem XPathItem for upstream functions, leading to a NotSupportedException NotSupportedException NotSupportedException at runtime.
- The in-scope namespaces of a constructed element did not include the empty prefix in some situations.
- The fn:element-with-id function gave incorrect results for schema-defined union types including xs:ID.

Version 1.0.2

Set default type checking mode to optimistic, as per documentation.
Fixed compatibility with XmlDocumentXmlDocumentXmlDocument
- Fixed NullReferenceException NullReferenceException NullReferenceException when using fn:data() caused by XmlDocument XmlDocument XmlDocument returning an IXmlSchemaInfo IXmlSchemaInfo IXmlSchemaInfo instance with null SchemaType SchemaType SchemaType.
- Fixed infinite loop caused by an XPathNodeIterator XPathNodeIterator XPathNodeIterator over XmlDocument XmlDocument XmlDocuments not consistantly returning false after the end of the node set.
- Fixed the XQuery version declaration for cultures where '.' is not the decimal point.
- Fixed normalization rules of general comparisons as per erratum XQ.E18.
For increased performance, the command line tool now runs in x86 mode by default.

Version 1.0.1

First full release.
